Good Day,
I do not use Power Flex much and I was called to troubleshoot one at a customer site. So if you have some advice I'd appreciate it.
They have a PF700. 240V 50/60HP. It continually trips out on HeatSink Overtemp. It is in a cool, pretty clean environment in the blower room at a WWTP and you can feel the internal fans blowing air out the top of the VFD.
yesterday it only ran about an hour before it tripped. I was unable to find in the menus what the temperature was at the time of the vfd fault.
Any advice on troubleshooting this fault? Is is possible the internal temp sensor is faulty?
